Golden Sedum (Sedum adolphi) is a low-growing succulent plant with pointed dark green leaves. The leaves develop orange or reddish tips when exposed to bright sunlight. Sedum adophi produces white, star-shaped flowers in spring. It can survive a few hours in temperatures as low is 29 degrees Fahrenheit, but is not considered winter hardy except in frost-free locations, such as United States Department of Agriculture plant hardiness zone 10 and warmer. Sedum adolphi is most often grown as a houseplant or an attractive outdoor container plant where it can be protected during the winter.
Step 1
Purchase a well-draining container for planting Sedum adolphi. The container should not be any bigger than 2 inches more in diameter than the root section of the plant. A larger container will contain more potting soil than is needed for the plant to grow. Unused potting soil collects moisture and the organic material in the potting soil will create fungal problems that can spread to the plant.
Step 2
Fill the bottom of the container with 1 inch of fine gravel. The gravel helps the container drain so it does not hold water. A Sedum adophi plant cannot sit in waterlogged soil or the plant will rot.
Step 3
Add potting soil until the container is half full. Carefully take the sedum from the previous container and plant in the new container. Add more potting soil around the Sedum adolphi until it is planted at the same depth it was planted in the previous container and the soil surface is 1 inch below the top of the container. Add water over the soil to settle the potting soil. Add more potting soil as needed. Spread a 1/2-inch layer of gravel over the potting soil. Leave a 1/2-inch space between the gravel and the top of the container so soil and gravel will not wash from the container during watering.
Step 4
Water the Sedum adolphi when the soil in the container is dry. Test the soil for dryness by pushing your finger through the gravel mulch into the top inch of soil. Water heavily until water runs from the bottom of the container.
Step 5
Fertilize once a month with a one-fourth strength solution of water soluble fertilizer appropriate for container plants. Only fertilize during the spring and summer months when the plant is actively growing.
Step 6
Place the container in which the Sedum adolphi is planted in a brightly lit location in the house. Outdoors, place the Sedum adolphi where it is protected from the hottest afternoon sun. Direct sun in the first part of the day followed by shade or dappled sun is best.

Succulent jade plants are popular houseplants because they are easy to care for and rarely suffer from pests or diseases. A healthy jade plant has plump, green leaves with glossy surfaces. If your jade plant has white dots or spots on its leaves, this could be a sign of insect infestation or incorrect growing conditions. Investigate any potential problem straightaway before it has a chance to spread.
Mealy Bugs
Mealy bugs are small, soft-bodied insects up to 1/4 inch long. They are covered with a layer of white dust or filaments that are mobile. Mealy bugs gather on new stems and on the undersides of jade plant roots. Treat mealy bugs by dabbing them with a paintbrush dipped in a 70 percent solution of rubbing alcohol. Deal with severe infestations by using a systemic insecticide formulated for houseplants.
Salt
Jade plants naturally develop small crystals of salt on their leaves. The salt is absorbed through the roots and excreted by the leaves. It dries into small, white dots. You can't prevent these but you can remove them with a damp cloth. Flush out the soil of your jade plant with plenty of water if it is covered with a white crust of salt.
Oedema
Jade plants that receive too much water suffer from a condition known as oedema. The first symptom is develop blisters on the leaves. These pop and form small, corky spots that go from yellowish-white to brown. Reduce watering of jade plants showing signs of oedema. The spots that are already present are permanent but no new ones will appear. Oedema is most common on jade plants during the winter.
Other Causes
Water drops drying on jade plant leaves leave white spots on their surfaces, especially in hard-water areas. Wipe them off with a damp cloth. Jade plants exposed to household chemical sprays or hot cooking oil may also develop discolored spots on the leaves. Indoor jade plants kept in a humid room such as a bathroom sometimes develop powdery mildew on their leaves in the winter. Decrease the local humidity levels or increase the airflow around the plant to prevent it from growing again.

Succulent plants tend to have tough leaves and stems rarely troubled by pests. Insects, however, sometimes infest new growth and can cause long-term disfigurement. Small black insects on succulent plants could be aphids or ants associated with them, or hempitera bugs. Indoor potted succulents can also host sciarid flies in their soil.
Aphids
Black aphids or blackfly infest the young leaves and flower shoots of succulents. They are small, soft-bodied insects up to 1/16 inch long and form colonies. Treat aphids with a spray based on insecticidal soap. Clemson University horticulture specialist Janet McLeod Scott advises testing any chemical on a small section of your plant and leaving it for 48 hours to make sure it is not toxic.
Ants
Ants do not damage succulents but may visit them to feed on the nectar in flowers. Ants also feed on a sweet substance produced by aphids and in return, tend aphid colonies and protect them from predators. Remove ants from succulents by treating the aphids that attract them.
Sciarid Flies
Sciarid flies or soil midges are tiny flying insects that live in damp soil and leaf litter. They are not common around succulents because they favor damp soil but can be a nuisance around indoor succulents. Sciarid fly larvae occasionally feed on the roots and lower stems of succulent plants. Treat sciarid flies by allowing the soil around your succulents to dry out and by avoiding peat-based composts.
Hemiptera Bugs
Hemiptera bugs are small, mobile insects with sucking mouthparts. Several species feed on succulents such as yuccas and cacti. Among them, Hesperolabops gelastop has a reddish colored head and blackish body. It lives in small groups on the upper surfaces of succulent leaves and causes pale blotches up to 1/2 inch across. Some yucca plants have Halticotoma bugs infestations, according to Texas A&M University professor Bastiaan M. Drees. They are 1/4 inch long with dark-gray bodies. Halticotoma bugs live in groups and scatter quickly when disturbed. Treat hemiptera bugs with a systemic insecticide containing dinotefuran or imidacloprid, applied in the spring.

Cacti are slow-growing succulent plants with well-developed vascular systems, or systems that transport food and water through the system. Thanks to this system, if a piece breaks off the cactus, there are several options to salvage it, whether it is grafting or planting the piece as a new specimen.
Grafting
Broken pieces often have jagged edges and damaged tissues, so if you were to simply put the broken piece back onto the cactus and bind it in place, chances for success are low. If the wounded end on the broken piece and the stub were cut evenly with a sharp knife and you bind the broken piece into place on the stub, the chances of the cactus healing are much greater. This is because of the ease of grafting cactus plants and the very high probability of cacti of the same species grafting successfully. Alternately, you may graft the broken piece onto another cactus, preferably of the same species.
Planting Pieces
You can also plant broken pieces to create new cacti. It is best, however, to let the broken piece scab over for a few days in a warm, dry area with good circulation to prevent problems with fungal disease entering along the broken edge. Alternately, you may dip the broken edge in an anti-fungal sulfur solution. If the piece broke off because of disease or infection of the main plant, remove the diseased parts with a sharp, disinfected knife first, or the disease will claim the broken piece as well.
Aesthetics
Grafting leaves scars. This isn't a big problem if you have a sectioned cactus and it was a whole section that broke off. For many cacti, however, a broken section grafted back into place looks wounded, even if the graft heals. It may be better to trim the stub back to a section further down or closer to the main section of the cactus, depending on the type of cactus, and then re-attach the broken piece. If you will plant the broken piece for a new cactus or simply dispose of it altogether, it helps to trim the cactus, if possible, to remove jagged edges or odd-looking stumps.
Considerations
If the break is next to or on the base of the cactus, it is usually easier to simply allow the broken cactus piece to scab over and then re-plant it rather than try to get a graft to take. The wound is susceptible to fungal infection, especially if the soil is moist or comes into contact with the grafting joint.

The starfish cactus is also called carrion flower due to the strong unpleasant odor of its fleshlike flowers. The plant is a succulent from South Africa with starfish-shaped flowers and long, slender, spiked branches. The flower attracts flies not only with its potent smell but also with the soft white fur that covers the flower and resembles mold covering rotting flesh. There are about 100 species in the plant's family, Asclepiadaceae, which includes several other fly-attracting blooms.
The Cactus
Several varieties of the starfish cactus exist. They all have the green branching arms that are tinged red in high-sun situations. The arms are barbed with thick white spines. The stems have four angles arrayed up the length and are an inch thick on average. The plant itself reaches 9 inches tall and has a wider spreading habit. Some of the varieties of cactus are considered rare in South Africa, a condition caused by loss of habitat.
Carrion Flowers
The flowers of the starfish plant may extend 10 inches across. The flowers are five-pointed and flesh-colored, although some have a grayish cast and others have a rosy glow. The larger species bear flowers at the base of the plant and smaller blooming species may have flowers scattered over the cactus. Each flower only lasts a few days but may die out and become replaced by another bloom. The petals have a grainy texture and pores that resemble skin.
Bloom Time
The blooming time of starfish cacti depends on where they are being raised, the amount of sun and water they receive, the fertility of the soil and the variety. On average, you can expect a baby plant to bloom in two years with just one or two flowers. When it is mature, the plant will bloom successively in July to September in North America. They flower in November through March in South Africa where they are native. Blooms are rare and rely upon prime growing conditions.
Pollination and Fruit
The stench is the attracting part of the flower, but its resemblance to flesh actually confuses flies into laying their eggs on the interior. The interior structure of the flower is webbed, which traps the legs of the flies. As they struggle, a pollen packet is attached to the insect's leg and they move on to the next flower. After the flower has finished, it sheds the petals and the ovary swells. Eventually, it bears a number of slightly hairy seeds. Seed is easy to start, but the plant will not bear flowers for many years.

A succulent is a plant which can store water within its leaves or bulbs for a long period of time without the need of frequent watering like other plants. You can mail a succulent plant to someone and not have to be worried about the plant not receiving any water for a few days. Packaging the plant properly will ensure its safe journey. Check with your local Department of Agriculture of extension office about rules on sending certain types of plants to other states or countries.
Step 1
Obtain the succulent you wish to send at a garden center or dig it up from your own yard. Shake off any excess soil. Don't water it. Succulent plants will travel better with dry roots.
Step 2
Wrap the succulent in tissue paper. For succulents with spikes, wrap carefully in three sheets of newspaper. Make a label for each plant and tape on the paper. Make a warning note for any succulents that have spikes.
Step 3
Place the roots of succulents such as epiphytes, orchid cacti or Christmas cactus in a plastic bag containing a small amount of peat moss and secure it with twine. Wrap the foliage in tissue paper or newspaper.
Step 4
Place the wrapped succulent into an inner box and then into a sturdy shipping box. The inner box will provide more protection especially for the succulents with pointy leaves.
Step 5
Fill in any empty spaces with newspaper to prevent the movement of the items during shipping.
Step 6
Secure the outer box with three strips of pressure sensitive tape that is 2 inches wide. Apply on the top, the bottom and all seam of the box, according to Federal Express. Write "Perishable" on the box and address it appropriately. Mail the succulents overnight to ensure a quick delivery.

Cacti are fleshy, succulent plants that mostly come from the American continent. They store water in their stems that they use sparingly, and therefore, rarely need watering. They acquire water from their extensive, fibrous root systems that draw moisture from the soil through exceptional suction pressure. Cacti are flowering plants that differ greatly in shape and size. Spines, which are cacti's most notable feature, also vary greatly, with some species have long, brightly colored spines and others having short, sparse spines.
Rainforest Cacti
While the majority of cactus species are found in the hot, arid desert, a few species exist in rainforests. Orchid cacti have flat stems that resemble leaves and big bright flowers that vary in color. Holiday cacti bloom small flowers from long branching stems at Easter, Thanksgiving and Christmas. Rainforest cacti prefer cooler, shadier, wetter conditions than desert cacti.
Prickly Pear Cacti
Prickly pear cacti encompasses the largest genus with over 300 species growing in a wide range of regions from Canada to Argentina. They have flat, paddle-like stems with spines that can be short or long. Prickly pear cacti flower in a variety of colors that are large and wide and bear edible fruits. Light, nutrient-rich soil keeps prickly pear cacti happy, as well as a bright, warm area.
Columnar Cacti
Columnar cacti have tall, narrow, cylindrical-shaped stems with vertical ribs. Spike density, size and flowering varies with each species. As with other arid cacti, columnar cacti prefer dry, warm, bright conditions and little moisture.
Barrel Cacti
Barrel cacti are cylindrical, resembling the shape of barrels native to the American Southwest and high limestone altitudes of Mexico. They have strong, colorful, showy spines and flowers, and can grow up to 10 feet tall. They prefer loamy, slightly acidic soil and a warm sunny location. Barrel cacti also grow very slow and don't need much fertilizing.
Hedgehog Cacti
Hedgehog cacti get their name from their globular shapes that are densely covered in spines that make them resemble hedgehogs. Native to Mexico and the southwestern U.S., they have cup-shaped flowers that, unlike other cacti, don't close up at night. Hedgehog cacti like sunny, warm areas and are sensitive to moisture and should only be watered from the bottom.
Pincushion Cacti
The majority of pincushion cacti are found in Mexico, but also grow in other parts of Central America and areas of the U.S. This small, ball-like cactus puts on a magnificent display of star-shaped flowers and has a thick coat of spines. Pincushion cacti are tolerant of a variety of different soils and prefer dry conditions.

Succulent plants have thick, fleshy leaves that store water. Some varieties flower while others only produce attractive foliage and stems. Most succulents thrive in dry conditions because too much moisture can cause the plants to rot. Rocky soil that drains quickly works well for most succulent varieties. You can grow them indoors in a dish filled with gravel, which provides adequate moisture drainage, although some soil is still necessary to provide nutrients and a medium for the succulent roots.
Step 1
Fill a 3- to 5-inch-deep pot or dish with a one inch layer of gravel. Use a dish with no bottom drainage holes.
Step 2
Sprinkle a tablespoon of powdered activated charcoal over the top of the gravel layer. Charcoal prevents odors from developing in the moisture trapped within the the gravel layer.
Step 3
Place a peat-based potting soil on top the gravel, filling the dish to within 1/2 inch of the rim. Alternatively, make your own mix by combining two parts peat with one part compost.
Step 4
Water the soil layer until it is evenly moistened throughout. Stick your finger into the soil mixture to judge the moisture level.
Step 5
Plant the succulents in the potting soil. Set them so their roots are buried to the same depth. Spacing requirements depend on the specific plant type, but generally a 2- to 4-inch spacing is sufficient.
Step 6
Water the succulents when the potting soil layer is completely dry. Provide only enough moisture to slightly dampen the soil. The excess moisture drains into the gravel bed beneath the soil.

Miniature pine tree (Crassula tetragona) is a low-growing succulent shrub resembling a small pine tree, boasting a tree-like habit of bluish green, awl-shaped leaves and spring-blooming white flowers. A popular bonsai, miniature pine tree is often grown as a potted garden plant or houseplant, though it may also be grown directly in the garden where hardy. Aesthetically, miniature pine tree fits in well with rock gardens, bonsai plantings and zen-themed gardens.
Location
A native of South Africa, miniature pine tree is a heat-loving frost-sensitive plant, hardy to about 28 degrees Fahrenheit. It may be grown successfully outdoors in U.S. Department of Agriculture plant hardiness zones 9 to 11, where it will thrive in full sunlight or light shade. Provide indoor plants a winter dormancy period with temperatures around 48 degrees Fahrenheit.
Soil
Like other succulents, miniature pine tree requires very well draining soil. Poorly draining soil, coupled with excessive irrigation, is a surefire recipe for the often fatal fungal disease root rot. A mixture of sand, loam, pea gravel and peat moss with a pH between 6.1 and 7.8 is ideal. Fertilize once during the growing season with a balanced 10-10-10 fertilizer diluted with water to about half strength.
Maintenance
The low maintenance miniature pine tree requires water only once a month or so during the growing season, watering deeply, then allowing the soil to completely dry out before watering again. In the winter, water sparingly, just enough to keep the leaves from shriveling. Miniature pine tree may be propagated by leaf or stem cuttings, rooted in moist, well-draining potting media. The plant may also be divided during the growing season or grown by seed.
Problems
Members of the Crassula genus are prone to mealybugs -- small, cottony insects that form colonies on leaves. If left unchecked, they may stunt plant growth or invite unattractive black sooty mold. The University of California Integrated Pest Management Program recommends removing mealy bugs with a direct stream of water or applying insecticidal soap or narrow-range oil. Avoid excessive use of insecticides in the home garden, which can kill the beneficial insects and parasites that prey on mealybugs.

BOTANICAL NAME: Aloe barbadensis
PLANT TYPE: Houseplant
SUN EXPOSURE: Part Sun
FLOWER COLOR: RedYellow
The Aloe Vera plant is an attractive succulent with thick, variegated leaves that fan out from its center base. Aloe vera plants are easy to keep and useful, too, as the juice from their leaves will relieve pain from scrapes and burns when applied topically. Keep the aloe vera plant in a pot near a kitchen window for everyday use.
PLANTING
Plant in wide containers with a well-draining potting mix, such as those made for cacti and succulents. Aloe vera plants are hardy, but a lack of proper drainage can cause rot and wilting.
Place in indirect sunlight or artificial light.
CARE
Water aloe deeply, but in order to discourage rot, allow the soil to dry at least 1 to 2 inches deep between waterings. Water even less often in winter.
Aloe vera plants produce offsets—also known as plantlets or “babies”—that can be removed to produce an entirely new plant.
Knock your aloe vera out of its pot and find where the offsets are attached. Sever them from the mother plant with a knife. Allow the cuts on the offsets and the mother plant to callus over for a day or two, then pot them in a standard potting mix. Put in a sunny location. Wait a week to water and keep the soil on the dry side.
PESTS/DISEASES
Aloe vera plants are susceptible to common garden pests, such as mealybugs and scale.
Some common diseases are root rot, soft rot, fungal stem, and leaf rot. Avoid overwatering to prevent these conditions from developing.

Succulents are booming in popularity for two simple reasons: they are beautiful and nearly indestructible.
Technically, a succulent is any plant with thick, fleshy (succulent) water storage organs. Succulents store water in their leaves, their stems or their roots. These plants have adapted to survive arid conditions throughout the world, from Africa to the deserts of North America. Fortunately for us, this adaptive mechanism has resulted in an incredible variety of interesting leaf forms and plant shapes, including paddle leaves, tight rosettes, and bushy or trailing columns of teardrop leaves.
As a group, succulents include some of the most well-known plants, such as the aloe and agave, and many almost unknown plants. Cacti are a unique subset of the succulent group. Succulents make excellent display plants in dish gardens.
The Rules for Growing Succulent Houseplants
No matter what kind of succulent you're growing, the rules are pretty similar between the different species. Here are the general rules for growing top-quality succulents:
Southern Light
Succulents prefer bright light, such as found on a south-facing window. Watch the leaves for indications that the light level is correct. Some species will scorch if suddenly exposed to direct sunlight. The leaves will turn brown or white as the plant bleaches out and the soft tissues are destroyed. Alternatively, an underlit succulent will begin to stretch, with an elongated stem and widely spaced leaves. This condition is known as etoliation.
The solution is to provide better light and prune the plant back to its original shape. Many kinds of succulents will thrive outdoors in the summer.
Temperature
Succulents are much more cold-tolerant than many people assume. As in the desert, where there is often a marked contrast between night and day, succulents thrive in colder nights, down to even 40ºF.
Ideally, succulents prefer daytime temperatures between 70 F and about 85 F and nighttime temperatures between 50 F and 55 F.
Watering
Succulents should be watered generously in the summer. The potting mix should be allowed to dry between waterings, but do not underwater. During the winter, when the plants go dormant, cut watering back to once every other month. Overwatering and ensuing plant rot is the single most common cause of plant failure. Be aware, though, that an overwatered succulent might at first plump up and look very healthy. However, the cause of death may have already set in underground, with rot spreading upward from the root system. A succulent should never be allowed to sit in water. The following are signs of under- or overwatering:
Overwatering. Overwatered plants are soft and discolored. The leaves may be yellow or white and lose their color. A plant in this condition may be beyond repair, but you can still remove it from its pot and inspect the roots. If they are brown and rotted, cut away dead roots and repot into drier potting media, or take a cutting and propagate the parent plant.
Under-watering: Succulents prefer generous water during the growing season (spring and summer). An under-watered plant will first stop growing, then begin to shed leaves. Alternatively, the plant may develop brown spots on the leaves.
Potting Soil
Succulents should be potted in a fast-draining mixture that's designed for cacti and succulents. If you don't have access to a specialized mix, consider modifying a normal potting mix with an inorganic agent like perlite to increase aeration and drainage. These plants have shallow roots that form a dense mat just under the soil surface.
Fertilizer
During the summer growing season, fertilizer as you would with other houseplants. Stop fertilizing entirely during the winter.
